Exploring the Unpleasant Iodine Flavor in My Mouth

3/2/2026, 4:00:26 AMMale25-34

Greetings! I am 19 years old and identify as intersex. Lately, I have been noticing an iodine-like flavor lingering in my mouth. I take good care of my teeth, brushing and flossing twice daily. My diet is low in red meat, yet I observe that the iodine taste intensifies when I do consume it. My familiarity with the taste of iodine stems from having had a total thyroidectomy at the age of 12, during which I was required to drink pure iodine for my parathyroid function. This strange taste resembles that experience. Currently, I am not taking any dietary supplements, although I do have some autoimmune conditions that do not necessitate medication. At present, I only take levothyroxine. Despite all this, I remain perplexed regarding the cause of this persistent taste. It doesn't seem to be an iodine overdose, but I wonder if my body might be inefficient at processing foods rich in iodine naturally?

Experiencing an iodine-like flavor in your mouth can certainly be concerning, especially given your medical history and autoimmune conditions. This phenomenon could arise from several factors. It is important to consider that since you've had a total thyroidectomy and are on levothyroxine, any fluctuations in your thyroid hormone levels or issues related to iodine metabolism could contribute to this unusual taste.

Explanation: The persistent iodine taste can be linked to various conditions, including:

  • Thyroid Hormone Levels: Since you are on levothyroxine, it’s crucial to ensure that your thyroid hormone levels are stable. High or low levels can impact taste sensation.
  • Diet and Taste Bud Sensitivity: Certain foods, including fish or seaweed, can have high iodine content, and even if you're avoiding red meat, they could influence taste if consumed.
  • Medication Effects: Some medications can alter taste perception, including levothyroxine, although this is less common.
  • Lack of Saliva or Dry Mouth: Reduced saliva production can intensify taste sensations, so consider hydration and oral care practices.
  • Autoimmune Conditions: Conditions like lupus can sometimes cause changes in taste due to systemic inflammation.

Next Steps:

  1. Monitor Your Symptoms: Keep track of when the iodine taste occurs, what you are eating, and any other concurrent symptoms. This diary can help correlate the taste with dietary or medication patterns.
  2. Stay Hydrated: Ensure you drink enough water throughout the day to help maintain adequate saliva production, which can help with taste sensations.
  3. Balance Thyroid Medication: Ensure that you are taking your levothyroxine correctly; this means taking it on an empty stomach and waiting at least 30-60 minutes before eating.
  4. Evaluate Diet: If you eat foods high in iodine, such as dairy, fish, or iodized salt, take note of their effect on the taste you’re experiencing.
  5. Consider Oral Care Products: Using fluoride mouthwash or a moisturizing mouth spray can help alleviate taste issues stemming from dry mouth.
  6. Test Thyroid Levels: If the taste persists or worsens, consider discussing with your healthcare provider the possibility of testing your thyroid hormone levels and discussing your symptoms.

Should the taste become persistent and bothersome or if you experience other symptoms, it may warrant a further discussion with a healthcare provider for a thorough evaluation. Remember, you’re not alone in this, and keeping a close eye on your symptoms will be key in managing your health.

When is it Safe for My Girlfriend to Be on Top Again?

I'm a 21-year-old male and my girlfriend is also 21. I suffered a fractured lower jaw nine weeks ago, which resulted in two fractures. Surgeons placed two titanium plates and screws to stabilize my jaw. As of now, I'm pleased to report that my recovery has gone well; I’ve resumed eating and leading a nearly normal life. I'm curious to know if it’s safe for her to sit on my face following this jaw surgery. I have not taken any medications since the second week after the operation, and my healing process has been excellent. I would really appreciate any advice on this matter. Thank you!

Concerns Regarding Endometriosis or Ovarian Cysts?

Hello everyone, I’m a 41-year-old female taking several medications, including Rhapsido for chronic hives and Dutasteride for hair loss. I also use a combination birth control pill, Blisovi FE 1/20. I mention Rhapsido and Dutasteride because they may contribute to my symptoms, and I want to eliminate any potential causes. Last June, I decided to stop taking birth control to restore my hormonal balance naturally, partly due to my diagnosis of Hashimoto’s thyroiditis. Unfortunately, this led to increased hair loss and worsening mental health, which prompted me to resume the same birth control pill in November to stabilize my hormones. I began the hair loss treatment in December and started the Rhapsido for hives in January. Both of these medications have side effects that can include irregular bleeding. Recently, I experienced light spotting followed by a brief period of discomfort in my lower right abdomen. Typically, I don’t have periods since I take my birth control regularly. Initially, I suspected the bleeding might be due to the hives medication, which is also causing some bruising, but the abdominal pain has left me uncertain about the cause. From my research, I’ve learned that conditions such as endometriosis, ovarian cysts, and PCOS can lead to irregular bleeding and pain, even when on birth control, and that some of these conditions may resolve spontaneously. My main concern is whether the irregular bleeding will cease before a potential cyst resolves or if it will continue until the cyst is fully healed. I have doctor appointments this week—one with a dermatologist regarding my hives and another with my primary care physician to discuss the possibility of a cyst. I've had a transvaginal ultrasound in the past, but they were unable to locate my ovaries, and it was quite painful. I’m wondering if there are other imaging techniques that provide better visualization of my ovaries and uterus than that ultrasound.
